Because there are no serious doubts. There's no real evidence for any of this. There might -- MIGHT -- be some argument to be made that having a non-American father might make you a ... non-natural-born citizen -- but there's NOTHING that seriously suggests he was born anywhere but in Hawaii, and the continual claims of that non-issue have really made it impossible to intelligently discuss the first, POSSIBLE issue of his father's citizenship. (Which, separately, as best I can tell, wouldn't preclude an American-born person from being considered natural-born, based on case law.)
The attorney who filed the Donofrio case has steadfastly avoided the BC issue and forthrightly states he believes Obama was born in Hawaii.
I agree with you that the BC issue is complicating discussion of the potential actual legal arguments. So stop talking about it!
BTW, I can guarantee you that perusing the “caselaw” for a few minutes is not going to give you an accurate answer as to how one’s father’s citizenship, especially under the facts at hand, impacts one’s status as a natural born citizen.
You seem to be suggesting that we should assume that Obama is a natural born citizen until proven otherwise. That is the wrong way to approach the issue. Since the Consitituion REQUIRES that the President be a natural born citizen, potential Presidents must prove their eligibility (notwithstanding the apparent lack of a a specific mechanism to do so).
Given that Obama has refused to provide a long form birth certificate that demonstrates where he was born and given the fact that supposedly his paternal grandmother says he was born in Kenya, in my view the appropriate course of action for the SCOTUS is to simultaneously create a formal process under which presidnetial candidates prove their eligibility and immediately require that Obama comply with that process.
By your suggested standard, virtually anyone who does not have a foreign birth certificate floating around in the public domain could run for the U.S. Presidency, which of course is ridiculous
